Bugfix: not just SunOS, but also FreeBSD, has a too-small limit on
the number of open files a process can hold. This can cause
problems when compiling nhc13comp with hmake.
The work-around from 0.9.3 is now applied universally, regardless
of operating system.

Bugfix: At last, the nhc13 version of GreenCard has parse error messages!
Previously, it simply failed silently, with truncated output
files.

Bugfix: installed version of hmake referred to temp include directory
instead of installed directory.

Release 0.9.3 (980706) features

Bugfix: Compiling for tracing under SunOS no longer requires an explicit
-lsocket.

Bugfix: SunOS has a very small limit on the number of open files a
process can hold. This caused problems when compiling
nhc13comp with hmake. It now has a work-around.

Bugfix: there was a GC bug in the Binary library, rarely causing a
segmentation fault.

Bugfix: the Prelude definition of product was wrong.

Bugfix: GreenCard now permits limited use of the Word type.

Release 0.9.2 (980624) features

Major addition: the tracing compiler and trace browser are now
available!

Major addition: source-level time profiling is now available.

Addition: a new compile-time option: -d objdir

Addition: the nhc13make and hbcmake tools have been
replaced by hmake. (New features: it generates build
scripts using any of hbc, nhc13, or ghc; it knows about cpp
directives; it knows about separate objdirs.)

Bugfix: object files are now built in separate directories from the
source tree. This means you can build simultaneously on different
architectures sharing the same sources.

Beta release 980501 features

Beta release 980327 features

Addition: a library for binary arrays, BinArray, has been revised and
added to the distribution.

Addition: the efficient bulk-transfer operation copyBin has
now been added to the Binary library.

Bugfix: GreenCard now treats functions of type ()->IO a
correctly.

Bugfix: there are some additional options to the config script.

Beta release 980320 features

Mainly bugfixes in the new configuration/installation script,
particularly installation of nhc13make, and better
handling of re-compilation in the presence of errors.

Some minor library bugfixes: Array is now an instance of Functor
(i.e. you can use map on an array rather than the old
amap); in GreenCard, the null string is now converted
to an empty string; the limit on ForeignObj's is now extended to
1024.

Beta release 980304 features

A complete overhaul of the installation scripts, particularly for
the C source distribution: there is now much greater automation of
configuration, build and installation.

The treatment of big- vs. little-endian architectures is now fully
automatic.

Beta release 980212 features

The binary libraries have been completely re-implemented (again).
The new version unifies memory compression and binary I/O into
a single `Binary' class. The old interfaces are still
available, but there are many benefits to the new design.

Bugfixes in the nhc13 version of the greencard
tool: it now understands `%const'
directives; and user DISs with multiple parameters (e.g.
`<fr/to> a b c') are now handled correctly.

Bugfixes in the installation scripts for the C source distribution
(which is now beta quality):
the makefile now correctly builds the runtime and prelude
before the compiler which must be linked with them; and
the freshly-built compiler now uses the ANSI-C backend by default.

A couple of other minor compiler bugfixes have been incorporated.

Beta release 971219 features

I have just added an (alpha-quality) distribution package which
requires only an ANSI-C
compiler (for instance, gcc) to build nhc13. This
should make nhc13 an extremely portable Haskell compiler. It
was made possible by a new compiler back-end (beta-quality) which
generates ANSI-C. The intention is to allow easy cross-compilation
(e.g. for embedded systems). We will be testing the cross-compiler
in early 1998.

Alpha release 971106 features

When you use the nhc13 or nhc13make commands,
GreenCard will be
called automatically if the file you are compiling has the extension
.gc.

The Compress and BinIO libraries have been
completely re-implemented using GreenCard. As well as
being faster all round, it is now possible
to interleave random-access reading and writing on the same file.
